Abstract: An apparatus for automatically adjusting a collection of images based on their lighting conditions is provided. The apparatus obtains one or more images, determines a first lighting condition scores for each lighting condition and for each of the one or more images using a trained prediction model, and labels the each of the one or more images based on the determined first lighting condition scores.

Abstract: An image processing apparatus and method for generating a sub-pixel alignment estimate from dual-pixel sensor data is provided. The method includes parametrically fitting at least two signals observed across a two dual-pixels of the dual-pixel sensor in the direction of the dual-pixel split. generating at least one bilinear measure on the at least two signals' fitting parameters. determining an alignment confidence based at least in part on the at least one bilinear measure on the at least two signals' fitting parameters, and determining the sub-pixel alignment estimate based at least in part on the at least one bilinear measure on the at least two signals' fitting parameters.

Abstract: An image processing apparatus is provided and includes one or more processors and one or more memories storing instructions that, when executed, configures the one or more processors, to receive a captured video from a camera capturing a meeting room, extract and store a predefined region of the video as extracted image data, generate a first corrected image by performing first image correction processing on the extracted image data to correct noise and generate a binary mask of the first corrected image, generate a filtered image based on the binary mask of the first corrected image and the first corrected image, generate a second corrected image by performing second image correction processing on the filtered image; and perform blending processing that combines the second corrected image with the first corrected image to generate a final corrected image.

Abstract: An information processing apparatus and method for relighting captured images in a virtual reality environment is provided. Righting processing performed by the apparatus includes acquiring an input image, acquiring a target image, determining at least one shared reference region for the acquired input image and at least one shared reference region for the acquired target image, determining a transform matrix based on the color space of the shared region, applying the transform matrix to at least a portion of the acquired input image, outputting the transformed portion of the acquired input image, and displaying the outputted transformed portion of the acquired input image.
